Unsinkable U-boats!
The U-boat was actually schnorkeling and the sound of the diesels attrackted the british submarine. After 30minuntes the masts of the U-boat were visible and plotted. The british fired 4 torpedoes at 1000yds and got 1 hit!
As a matter of fact in WA mod in SH3, I had spotted a submerged wolfpack along the coast of Portugal (noise first then several periscopes). I plotted and fired against one U-boat to see what will happen. The torpedo hit near the steering rudder but the u-boat didn't sink!
